3 Claims.

` p This invention relates to improvements in door holders. The object of the invention is to provide a generally improveddoor holder of simple efcient design and sturdy compact construction.

`Inthe accompanying drawingy illustrating the invention Fig. 1 isa view showing the door holder applied to a door the latter being shown in open position with. parts `broken away and parts in section.

Fig. 2 is a plan View ofFigL 1. I

Fig.l 3 is a full size sectional view of the door holding mechanism, the section being taken substantially on 4the `line 3--3 of Fig. 4.

` Fig. 4 is another full size sectional view of the door holding mechanism taken substantially on the line 4--4 of Fig. 3.

Fig. 5 is a bottom view of parts shown in Fig.

` 4 looking in direction of the arrow 5.

In the drawing the reference numeral I designates the door frame and II the door hinged at I2. The door holder comprises a main bracket I3 which is let into a recess I4 in the top of the door being secured thereto by screws as indicated at I5. The bracketIB comprises a channel I6 to which there is secured a housing which is made in two parts I'I and I8. The part I'I is secured to the bottom of the channel I6 by screws as at I9 and forms a main support for the parts of the door holding mechanism. At

1 the inner end of the bracket part II it forms an Cil abutment 39 for the one end of a spring 20 the other end of which acts against a sliding abutment 2|. The movement of the latter is limited by a screw 22 which projects into a slot 23 in the part I'I. The latter also forms a bearing 24 for the vertically slidable door holding bolt 25. The latter is normally urged upwards into door holding position by a spring 26 the tension of which may be regulated by a lever 21. 'I'he latter is pivoted at 28 on a screw which passes through the parts I'I and I8, see Fig. 5. The lever rests upon a pin 29 in the bracket, being held against said pin by the spring. The lever f may be raised by means of an adjusting screw 30 which has a tapered head 3I adapted to engage the lever 21 to raise or lower the same in an obvious manner whereby-to adjust the pressure of the spring 26.

The bolt 25 has a tapered head 32 adapted to be engaged by a sliding catch 33 which slides in the channel I6 and is provided with a cam surface 34 so that the catch can pass in over and ter in a recess 35 in the catch. The latter is pivoted-at 36 to an arm 3'I the other end of which is pivoted to av plate 38 secured to the door casing II as shown.

Figs. 1 and 2 show the door'in open position."`

It will be seen that in this position the door is""'5 normally held rmly by the engagement of the catch 33 with the bolt 25. When however undue strain is exerted to close the door, the catch 33 will be moved outward inthe channel I6 andJ automatically depress the bolt 25 and the door may then be closed. The degree of holding power is controlled by adjusting the spring by the screw When free opening and closing of the door...

is desired the bolt may be moved down into" inaction position by means of a locking lever 40 which is pivoted upon a screw 4I and extends into a slot 42 in the bolt. The locking lever is engaged by a rotatable latch bolt 44 which is operable from the outside by a control knob 45. In Figure 4 the latch bolt 44 is turned so that the locking lever is moved up into a recess 46 in the bolt. Consequently the `holding bolt can move up into door holding position by the spring 26. When however the latchfbolt is rotated 180 by the knob 45, the locking lever is depressed and moves the holding bolt 25 down against the pressure of the spring. The holding bolt is now no longer free to move up into door holding position and the door may be freely opened and closed. The spring 2l] serves as a shock absorber against the slam of the sliding catch 23 when the door is opened and the catch is moved in over the holding bolt 25.

When the parts are assembled the bracket part I8 fits against the part I'I as shown in Figure 5 to form a housing and the spring 20 is covered by a plate 6U. The two screws 28 and 4I hold the parts together. A cover plate 50, Fig. 3, completes the installation of the door holder and provides a neat iinished appearance.

The door holder may be used for either right or left hand doors as well as for double acting doors when desired.

In operation the door holding bolt 24 may be in its lower or in its upper position depending upon the position of the recess 46 in the latch bolt. If the latter is turned as in Fig. 4, the holding bolt 25 will project upwards into the channel I6 and will then be engaged by the sliding catch 33 to automatically hold the door in open position. If the holding bolt should have been moved into its lower inactive position, it may be raised after the door is opened by merely turning the knob 45 as to bring the recess 46 lowermost. Again, with the door in open position and held by the bolt 25 the latter may be withdrawn from the sliding catch 33 by turning the knob 45 to bring the recess 46 uppermost. Thus the door holder may be easily manipulated to suit local conditions and requirements. door holder includes therefore mechanism whereby the holding bolt will automatically be engaged by the sliding catch to hold the door under normal conditions, yet yield to free the door under excessive strain. By operating the knob 45 the holding bolt may bepermanently or temporarily held in lowered inactive position or be left free to engage the sliding catch.

I claiml. A door holder comprising a guide structure and including a channel means for attaching the same to the top edge of a door, a catch slidably movable in the channel, an arm having onev end pivoted to said catch, means for pivoting the opposite end to the door casing, a bolt in said guide structure, a spring for moving said bolt into an operative position within the channel to engage said sliding catch in the position corresponding to the open position of the door, means enclosed in the channel for cushioning the movement of the catch into open door position, a lever in said guide structure for moving said bolt into an inactive position against thesaid spring and for releasing the bolt to be actuated by said spring, a rotatable member for operating said lever and a knob connected to said rotatable member for manually operating the same.

,2. A door holder comprising a guide structure including a channel means for attaching the The v same to the top edge of a door, a housing secured to the channel below the same, a vertically movable bolt in the housing, a spring for moving said bolt to project into the channel from below, a catch slidably movable Within the channel and adapted to be engaged by said bolt in the position corresponding to the open position of the door, means within said housing for locking the bolt in inactive position below the channel against the said spring and for releasing the bolt to be moved by the spring, means for actuating said locking and releasing means and an arm pivotally Y connected to the said catch and to the door casing.

3. A door holder comprising a guide structure including a channel, a catch slidably movable Within the channel, an arm pivotally connected to said catch, a housing secured to said channel within the door, a vertically movable bolt in said housing, a spring for moving said bolt up into the channel in the path of said catch to engage the same in the position corresponding to the open position of the door, means in said channel for cushioning the movement of the catch into open door position, a lever pivoted in said housing and engaging said bolt to move it into an operative position to be actuated by the spring or into an inoperative locked position against the spring, a rotatable member in said housing for actuating said lever, a knob for actuating said rotatable member, a lever for supporting said spring in normally operative position and means for adjusting the position of said last named lever to regulate the tension of the spring.
